Design feature of the present utility model also is:
Being set to of described transmission mechanism: be on the body bearing of the same side a fixed axis is set with the anxious bar that stops of circuit breaker, suit one shift fork on fixed axis, the other end of shift fork and described power transmission shaft connect firmly, the spindle nose of described power transmission shaft runs through the feeding switch housing and stretches out in the outside of feeding switch housing, and described manual lever connects firmly on the spindle nose of power transmission shaft.
Form the fan-shaped latch plate that has of interlock with described power transmission shaft, in the periphery of described fan-shaped latch plate two lock slots that are on the different circumferential positions are arranged, one is the closed position lock slots, and one is to cut-off a lock slots; On described feeding switch housing, one scram button that has a return spring is set corresponding to the anxious place, bar position that stops of described circuit breaker, one locking disk is set on the axostylus axostyle of described scram button, and described fan-shaped latch plate is with the closed position lock slots on it or cut-offs a lock slots and be locked on the locking disk.
On described body bearing, roller is set, described body bearing be with roller wheel bearing on described slide rail.
Compared with the prior art the beneficial effects of the utility model are embodied in:
1, the utility model is at the circuit breaker that is connected to the wiring chamber in the mode of pegging graft, outer setting manual lever at housing, realized under the state that the flame proof door is not opened, directly plugging circuit breaker by peripheral operation, do not need to turn-off level power supply in the operating process, reduce the influence that other working face is brought because of higher level's power cut-off.
2, the mode of peripheral operation of the present utility model greatly facilitates for the circuit breaker maintenance and changes, and increases work efficiency.
3, the plug mode of connection of the utility model breaker body and wiring chamber is also with making enclosure interior safer because of outage.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the end view of Fig. 1;
Fig. 3 is another view of the utility model;
Number in the figure: 1 breaker body; The anxious bar that stops of 2 circuit breakers; 3 breaker plugs; 4 body bearings; 5 rollers; 6 fixed axis; 7 manual levers; 8 circuit breaker sockets; 9 socket insulation boards; 10 locking disks; 11 feeding switch housings; 12 power transmission shafts; 13 shift forks; 14 fan-shaped latch plate; 15 scram buttons.
Embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, present embodiment fixedly installs the body bearing 4 that can move forward and backward along the plug direction at the plug-in circuit breaker on slide rail in the bottom of breaker body 1; At the outer setting manual lever 7 of feeding switch housing 11, manual lever 7 drives transmission mechanism by the power transmission shaft 12 that runs through feeding switch housing 11, drives body bearing 4 moving on slide rail with transmission mechanism.
In concrete the enforcement, transmission mechanism is set to be on the body bearing 4 of the same side a fixed axis 6 is set with the anxious bar 2 that stops of circuit breaker, suit one shift fork 13 on fixed axis 6, the other end of shift fork 13 and power transmission shaft 12 connect firmly, the spindle nose of power transmission shaft 12 runs through feeding switch housing 11 and stretches out in the outside of feeding switch housing 11, and manual lever (7) connects firmly on the spindle nose of power transmission shaft (12).
In order to realize anxious stopping and the state locking, in the present embodiment, form the fan-shaped latch plate 14 that has of interlock, two lock slots that are on the different circumferential positions are arranged in the periphery of fan-shaped latch plate 14 with power transmission shaft 12, one is closed position lock slots 14a, and one is to cut-off a lock slots 14b; On feeding switch housing 11, one scram button 15 that has a return spring is set corresponding to the anxious place, bar 2 positions that stops of circuit breaker, one locking disk 10 is set on the axostylus axostyle of scram button 15, and fan-shaped latch plate 14 is with the closed position lock slots 14a on it or cut-offs a lock slots 14b and be locked on the locking disk 10.
